Summary

The goal of this clinical trial is to learn whether using a new Post-Dental Extraction Care Kit (PDEC-kit) can help patients better understand and follow their post-extraction instructions, and whether it can also reduce dental anxiety, compared with verbal instructions alone. The study is being conducted among adult patients (18 years and older) undergoing routine tooth extractions under local anaesthesia at a university oral surgery clinic.

The main questions this study aims to answer are:

Does the PDEC-kit improve patients' knowledge retention about post-extraction care?

Does the PDEC-kit improve patient compliance with important post-extraction behaviours (e.g., medication use, diet, activity restrictions)?

Does the PDEC-kit reduce patient anxiety compared with standard verbal instructions?

Researchers will compare two groups of patients:

One group will receive the usual standardised verbal instructions.

The other group will receive the same verbal instructions plus the PDEC-kit.

Participants in the PDEC-kit group will:

Watch a short educational video on post-extraction care.

Review illustrated flashcards showing key "dos and don'ts."

Observe a live demonstration using a dental model to learn how to place and bite on gauze correctly.

Take home a bilingual brochure (English and Bahasa Melayu), also available via QR code.

All participants will be asked to answer short questionnaires about their knowledge, behaviour, and dental anxiety at three time points: before the extraction, immediately after receiving instructions, and one week later.

Conditions

  • Tooth Extraction
  • Postoperative Complications
  • Patient Compliance
  • Dental Anxiety
  • Patient Education as Topic

Interventions

BEHAVIORAL

Standardised Verbal Instructions

Participants receive verbal post-extraction care instructions delivered by a trained investigator using a calibrated script. The content includes guidance on bleeding control, diet, oral hygiene, activity restrictions, and medication use.

BEHAVIORAL

Verbal Instructions + PDEC-kit

Participants receive the same standardised verbal instructions as the control group, supplemented with the PDEC-kit. The kit includes a two-minute educational video, illustrated flashcards, a live gauze demonstration using a dental model, and a bilingual (English and Bahasa Melayu) illustrated brochure with QR code access to a digital version.
